Abstract (from CDS):

Using spectroscopy from the Large Binocular Telescope and imaging from the Hubble Space Telescope we discovered the first strong galaxy lens at zlens> 1. The lens has a secure photometric redshift of z = 1.53±0.09 and the source is spectroscopically confirmed at z = 3.417. The Einstein radius (0.''35; 3.0 kpc) encloses 7.6x1010 M☉, with an upper limit on the dark matter fraction of 60%. The highly magnified (40x) source galaxy has a very small stellar mass (∼108 M☉) and shows an extremely strong [O III]_5007 Å_ emission line (EW0∼ 1000 Å) bolstering the evidence that intense starbursts among very low-mass galaxies are common at high redshift.
